Is it possible to iterate over dictionary keys?
问题
通过使用<dictionary_name>.keys字段，目前访问字典键的方法是通过该方法。但是，对于大型字典，这可能导致资源耗尽。我如何迭代字典的键，而不是将所有键作为数组返回？

However, this may result in resource exhaustion for large dictionaries.
How can I iterate over the keys for the dictionary, instead of all the keys as an array?
